Abstract: Improving the governance mechanism of community public sports services is an inherent requirement for constructing a higher-level public service system for national fitness. By adopting methods of literature review, field research and case analysis, this paper explores the type structure, operational dilemma and construction paths of the governance mechanism of community public sports services in China. The study finds that the governance mechanism of community public sports services can be summarized into the democratic consultation mechanism, fund-raising mechanism, voluntary service mechanism, supervision-evaluation mechanism, and digital support mechanism according to the staged logical relationship. On the other hand, operational dilemmas faced by these five types of mechanisms in practice are shown as follows: democratic consultation mechanism is trapped in procedural formalism; fund-raising mechanism overly relies on government investment; voluntary service mechanism has not been fully activated; supervision-evaluation mechanism suffers from insufficient social participation; and digital support mechanism plays a limited role. To improve the governance mechanism of community public sports services, the following suggestions are put forward: to standardize procedural operation and improve the effectiveness of democratic consultation; to integrate social resources and expand fund-raising channel; to optimize organizational structure and enhance the efficiency of voluntary services; to expand social participation and improve supervision-evaluation system; and to focus on platform construction and strengthen digital support capacity.
